Abstract
PURPOSE: To prepare a liquid prepolymer capable of giving a cured polymer dyeable without causing dyeing speck, by adding a specific amount of a radical polymerization initiator to diethylene glycol bisallyl carbonate, and keeping the mixture at a specific temperature.
CONSTITUTION: Diethylene glycol bisallyl carbonate is compounded with 0.3W2.3 wt% radical polymerization initiator (e.g. isobutyl peroxide) and maintained at 5W35°C for 6W72hr to obtain the objective liquid prepolymer.
EFFECT: Since the reaction is carried out at a low temperature, the gelation of the prepolymer can be minimized and the prepolymer can be poured easily into a glass mold.
